The floor is supported by a conventional rear undercarriage assembly 36, 36′ and has a landing gear 38, 38′ secured thereunder at a forward position. The top panel 32, 32′ and an upper portion of the sidewalls 24, 24′ are secured to a top rail 40, 40′, and the floor and a lower portion of the sidewalls 24, 24′ are secured to a bottom rail 42, 42′. A respective L-shaped extrusion 44, 44′ joins the front end of each sidewall 24, 24′ to the front wall 28, 28′ and a respective L-shaped extrusion 46, 46′ joins the rear end of each sidewall 24, 24′ to the hinges which connect the doors to the body 22, 22′.

Each sidewall 24, 24′ includes a plurality of vertical upstanding composite panels 48-48e; 48′-48e′. End of adjacent panels, for example, 48a and 48b; 48a′ and 48b′ are used in forming the novel joint 50, 50′ of the present invention. A first embodiment of the joint 50 is shown in FIG. 2 and is used to form the trailer 20 as shown in FIG. 1. A second embodiment of the joint 50′ is shown in FIG. 4 and is used to form the trailer 20′ as shown in FIG. 3. At least two panels are joined together by the novel joint 50, 50′ to form the sidewalls 24, 24′ of the trailer body 22, 22′. Typically, each panel 48-48e; 48′-48e′ is four feet in width, but can be longer or shorter depending on the application.

Attention is now directing to the first embodiment of the novel joint 50 shown in FIG. 2 which is used to form the trailer 20 shown in FIG. 1. For convenience in the explanation of the joint 50, the joint 50 is only shown between panels 48a and 48b and is described with respect thereto. It is to be understood that like joints 50 are provided between adjacent panels, 48 and 48a; 48b and 48c; 48c and 48d; 48d and 48e, to form each complete sidewall 24 as one of ordinary skill in the art would understand. Moreover, for convenience in explanation, the structure of the panels 48-48e is described with respect to panel 48a, with the understanding that the structure of each of the other panels 48, 48b-48e is identical in construction.

Panel 48a includes a plastic core member 52a sandwiched between an outer thin metal skin 54a and an inner thin metal skin 56a and bonded thereto by a suitable known adhesive or other like means. The outer skin 54a and the inner skin 56a are preferably approximately 0.026 inches thick. The skins 54a, 56a are preferably made of aluminum, galvanized, full hardened steel, such as AISI Grade E full hard steel because of its cost effectiveness, or the like. Preferably, the outer skin 54a is made of ASTM G90 galvanized steel and the inner skin 56a is made of ASTM G60 galvanized steel. Aluminum may be used, but it may be too soft for some purposes and strength and punch resistance are sacrificed, however, aluminum is lightweight. Each core member 52a is made of some type of compressible non-metal material, preferably thermoplastic, such as polypropylene or high density polyethylene. These materials are relatively inexpensive as compared to aluminum found in prior trailer wall constructions. In addition, because a composite panel 48a is used, the weight of the trailer construction is reduced over trailers having aluminum sidewalls.

The core member 52a has a first end 58a which slants from the interior of the trailer 20 to the exterior of the trailer 20 at an angle. A second end 60a of the core member 52a also slants from the interior of the trailer 20 to the exterior of the trailer 20 at an angle. The second end 60a may slant at the same angle as the first end 58a of the core member 52a as shown in FIG. 2.

The inner skin 56a of the panel 48a has a plurality of portions which are integrally formed with each other and are roll formed into shape. Specifically, working left to right in FIG. 2, the inner skin 56a includes a first extending portion 62a which is connected to and integrally formed with an intermediate side portion 64a which is connected to and integrally formed with an intermediate end portion 66a which is connected to and integrally formed with a second extending portion 68a. The intermediate side portion 64a abuts against and covers the side of the core member 52a, and the intermediate end portion 66a abuts against and covers the second end 60a of the core member 52a. Thus, the intermediate end portion 66a is angled relative to the intermediate side portion 64a. The first extending portion 62a extends outwardly from the first end 58a of the core member 52a a predetermined distance, preferably approximately one inch, and is flush with the intermediate side portion 64a.

The first extending portions 62a, 70a abut against each other along the length thereof. The first extending portion 62a of the inner skin 56a is slightly longer than the first extending portion 70a of the outer skin 54a and the end 78a of the first extending portion 62a is bent, by roll forming, around the end 80a of the first extending portion 70a to form a first radiused end 78a. The first extending portions 62a, 70a are preferably bonded together by suitable means, such as adhesive.

The second extending portions 68a, 76a abut against each other along the length thereof. The second extending portion 76a of the outer skin 54a is slightly longer than the second extending portion 68a of the inner skin 56a and the end 82a of the second extending portion 76a is bent, by roll forming, around the end 84a of the second extending portion 68a to form a second radiused end 82a. The second extending portions 68a, 76a are preferably bonded together by suitable means, such as adhesive.

To form the novel joint 50, a member 86, in the shape of a bar, is provided between and abuts against the first extending portion 70b of panel 48b and the second extending portion 68a of panel 48a. A plurality of rivets 88 are provided through the first extending portions 62b, 70b of panel 48b, through the member 86, and through the second extending portions 68a, 76a of panel 48a. A plurality of aligned apertures are provided through first extending portions 62b, 70b, the member 86, and the second extending portions 68a, 76a to accommodate the rivets 88. Otherwise, the member 86 is solid and extends the generally the entire height of the panels 48a, 48b. The member 86 is made out of suitable material, and preferably metal or plastic. The head 90 of each rivet 88 abuts against the first extending portion 62b of panel 48b. The end of the shank of each rivet 88 is upset and the resulting bloom 92 abuts against the second extending portion 76a of panel 48a. By providing the doubled first extending portions 62b, 70b on the interior of the sidewall 24 and on the doubled second extending portions 68a, 76a on the exterior of the sidewall 24, reinforcement is provided to the joint 50.

A generally V-shaped juncture results between second radiused end 82a and intermediate end portion 72b. A sealant 94 is provided along the length of the V-shaped juncture to prevent the entry of moisture into the interior of the trailer 20. The first radiused end 78b of panel 48b abuts against the intermediate end portion 66a of panel 48a such that a flush inner surface is provided along the length of first extending portion 62a, intermediate side portion 64a, first extending portion 62b and intermediate side portion 64b. The radiused ends 78a, 78b; 82a, 82b provide for a smooth surface on the respective interior surface and the exterior surface of the trailer 20 to deter an outside object, such as a forklift, from snagging the sidewalls 24.

Attention is now directed to the second embodiment of the novel joint configuration shown in FIG. 4 which is used to form the trailer 20′ shown in FIG. 3. For convenience in the explanation of the joint 50′, the joint 50′ is only shown between panels 48a′ and 48b′ and is described with respect thereto. It is to be understood that like joints 50′ are provided between adjacent panels, 48′ and 48a′; 48b′ and 48c′; 48c′ and 48d′; 48d′ and 48e′, to form each complete sidewall 24′ as one of ordinary skill in the art would understand. Moreover, for convenience in explanation, the structure of the panels 48′-48e′ is described with respect to panel 48a′, with the understanding that the structure of each of the other panels 48′, 48b′-48e′ is identical in construction. Finally, like reference numerals are used to denote like elements in the second embodiment as in the first embodiment, with a prime following the reference numeral.

Panel 48a′ includes a plastic core member 52a′ sandwiched between an outer metal skin 54a′ and an inner thin metal skin 56a′ and bonded thereto by a suitable known adhesive or other like means. The outer skin 54a′ and the inner skin 56a′ are preferably approximately 0.026 inches thick. The skins 54a′, 56a′ are preferably made of aluminum, galvanized, full hardened steel, such as AISI Grade E full hard steel because of its cost effectiveness, or the like. Preferably, the outer skin 54a′ is made of ASTM G90 galvanized steel and the inner skin 56a′ is made of ASTM G60 galvanized steel. Aluminum may be used, but it may be too soft for some purposes and strength and punch resistance are sacrificed, however, aluminum is lightweight. Each core member 52a′ is made of some type of compressible non-metal material, preferably thermoplastic, such as polypropylene or high density polyethylene. These materials are relatively inexpensive as compared to aluminum found in prior trailer wall constructions. In addition, because a composite panel 48a′ is used, the weight of the trailer construction is reduced over trailers having aluminum sidewalls.

The core member 52a′ has a first end 58a′ which has an outer portion which slants from the interior of the trailer 20′ to the exterior of the trailer 20′ at an angle and an inner portion which slants from the interior of the trailer 20′ to the exterior of the trailer 20′ at an angle, such that the outer portion and the inner portion meet at an apex which protrudes outwardly from the center of the core member 52a′.

To form the novel joint 50′, the second extending portion 108a of panel 48a′ is abutted against the first extending portion 110b. A plurality of rivets 88′ are provided through the second extending portions 116a, 108a of panel 48a and through the first extending portions 110b, 100b of panel 48b. A plurality of aligned apertures are provided through the second extending portions 116a, 108a and through the first extending portions 110b, 100b to accommodate the rivets 88′. The head 90′ of each rivet 88′ abuts against the exterior surface of the first extending portion 116a of the panel 48a′. The shank of each rivet 88′ is upset and the resulting bloom 92′ abuts against the second extending portion 100b of panel 48b′. By providing the doubled extending portions 116a, 108a; 110b, 100b on the exterior of the sidewall 24′, reinforcement is provided to the joint 50′.

The second radiused end 120a of panel 48a abuts against the first extending portion 110b and proximate to the first intermediate end portion 112b of panel 48b such that a flush outer surface is provided along the length of intermediate side portion 114a, second extending portion 116a, intermediate side portion 114b, and second extending portion 116b. A generally V-shaped juncture results between second radiused end 120a and intermediate end portion 112b. A sealant 125 is provided along the length of the V-shaped juncture to prevent the entry of moisture into the interior of the trailer 20′. The radiused end 120a provides for a smooth surface on the exterior surface of the trailer 20′ to deter an outside object, such as a forklift, from snagging the sidewalls 24′.

To complete the joint 50′ of the second embodiment, a generally U-shaped batten or member 126, made of metal, preferably 0.019 steel, is mounted against the inner second end portion 106a of panel 48a′ and against first end portion 102b of panel 48b′. The generally U-shaped member 126 has a planar base 128 and opposite legs 130, 132 which depend therefrom. The legs 130, 132 respectively abut against the inner second end portion 106a of panel 48a′ and against first end portion 102b of panel 48b′. The base 128 is flush with the intermediate side portions 104a, 104b. The juncture of the base 128 and each leg 130, 132 is radiused to prevent an outside object, such as a forklift from snagging on the junction. The U-shaped member 126 is installed by a mechanical clip (not shown) or by bonding with hot melt or two component adhesive 134. The bloom 92′ of each rivet 88′ thus sits between the U-shaped member 126 and the first extending portion 100b of panel 48b′ and is not exposed to the interior of the trailer 20′.
